I had my webmaster install the wordpress blog into my joomla website, but he was experiencing trouble with the search engine friendly urls. So he contacted the support, who was extremely friendly and helpful. The support fixed the problem and now the wordpress blog is running without any trouble. One thing I really like, too, is that the design of my Joomla Site was transferred without any problem to the wordpress blog, so it has got exactly the same look like my website. Great!
